lWATER-C LOSE'T.

SPECIFICATION forming part of Letters Patent No. 567,120, dated September 1, 1896. Application filed November 4, 1895. Serial No. 567,916. (No model.)

.To aZZ whom it may concern.:

Beit known that LALEXANDER D. FowLEE, of the city of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Water-Closets, of which the following is a speciiication, reference being had to the accompanying drawing, forming part hereof, wherein the igure is a vertical central section.

The principal object of this invention is to so construct a double-trapped siphon watercloset with jet trapped that it will start Siphoning at once, and will then after-iill the bowl to any height desired7 forming a complete double-trapped water-closet.

My invention consists in the use of an airpassage in the partition between the bowl of a double-trapped siphon water-closet and the air-space in rear of the bowl, having the top of this air-passage opening on the bowl side of this partition above the water in the bowl, and the bottom of this air-passage opening on the opposite or back side of the partition, trapped by and under the water in the bowl when the closet is at rest, as shown in the gure. y

The water-closet, as shown in the iigure, is in the common and usual form of doubletrapped siphon water-closets, with `trapped jet and slotted flushing-rim, with the exception of the air-passage H I in the partition Kl This closet is made with a bowl B, formed into a trap by the partition K, with a full and complete trap E under the bowl, arranged in the common way with the air-space D between the two traps. G is the trapped waterjet at the top of the air-space D, while J is the water-supply pipe to the jet and to the iushing-rim A, which is provided with the usual slots for washing the sides of the bowl.

E is the passage to the sewer, and C is the space or passage in rear of the bowl behind the partition K.

I-I I is an air-passage formed in the partition K, the top of this air-passage opening on the bowl side of the partition K in the gure, above the water in the bowl, and the bottom of this air-passage opening on the opposite or back side of this partition K, trapped by and under the water in that part of the bowl C when the closet is at rest.

Theoperation of this closet is as follows: The tank being pulled, the water rushing down into the upper part of the air-space D, and also into the bowl B, and with the atmospheric pressure on the surface of the water in the bowl,and in the space O back of the partition K, (applied through the air-passage H 1,) drives the contents of the bowl B at once f through the air-space D and lower trap E into the sewer F.

As soon as the water in the bowl B falls below the bottom of the air-passage H I the closet begins to draw in air through H I from the bowl, and continues to do so until the airpassage is trapped bythe water rising in the bowl from theafter-iill of the tank.

The last of the regular flow of water from the tank remains in the lower trap E, which trap, with .the trapped bowl B, filled to the point indicated by the after-fill water, makes a complete double-trap closet.

The atmospheric pressure, applied through the air-passage H I to the water in the bowl C back of the partition K, also prevents the water in the bowl B and C from being siphoned out of the bowl into the lower trap while the bowl is illing up, this effect being produced by equalizing the atmospheric pressure in the bowl B and C on both sides of the partition K. Having thus described my invention, I claim as new, novel, and useful improvements and desire to secure by entl l. A water-closet consisting of the combination of a trapped bowl, the soil-passage yleading therefrom, a lower trap in the soilpassage by which an air-space is formed-between the two traps, and an air-passage leading from the bowl and above the Water therein, down through the partition that makes the trap in the bowl, and opening into and below the water in the bowl back of this partition.

2. In a double-trapped siphon water-closet, the combination of atrapped jet of water, discharged into the air-space between the traps, in combination with an air-passage leading from the bowl and above the water therein, down through the partition that forms the trap in the bowl, and opening into and below the water in the bowl back of this partition.
